Brian May announces 'the most epic Christmas track ever that's two years in the making'

Aside from his best-known work as Queen guitarist, Sir Brian May enjoys the occasional duet with other stars.

Most recently, he performed Who Wants To Live Forever with Andrea Bocelli, which is set to be released in November.

And now the 78-year-old rocker has announced a new Christmas single with his regular collaborator, X Factor finalist Talia Dean.

Posting a teaser clip on Instagram, Sir Brian wrote: "Only the most EPIC Christmas track EVER !!! And available in November - so you have plenty of time to assimilate its treasures. It's a tour de force - a beautifully simple but powerful and joyous song of praise for Christmas written by Talia herself. Yea, I DID have something to do with its production - we have been excitedly working on this secretly since before LAST Christmas !!! It will be so worth the wait. Watch this space --- for there is much more to come !!! Merry .... erm ... OK I'll hold off on that for now !!! ENJOY !!!! Bri."

Talia wrote on her on Instagram: "I will be releasing a Christmas single this November to celebrate the birthday of Christ. I feel so blessed to have a beautiful gospel choir and Sir Brian May's support on this record. It's been almost two years in the making."
